When do we use w= -Pexdelta v? When do we use w=-nRT ln (V2/V1)?

You use w = - pex∆V when external pressure is constant. You use w = - nRT ln(V2/V1) when pressure is variable, or not constant.

Use w=-PdeltaV for irreversible systems (constant P) and use w = -nRTln (V2/V1) for reversible processes when P is not constant.

The first is for irreversible reactions and the latter is for reversible reactions.
